Linux Power Management Features and Their Interactions - Part 2

Explore advanced Linux kernel power management features and their complex interactions in this 41-minute conference talk from the Linux Foundation. Delve into sophisticated power management concepts including system-wide suspend wakeup sources, device and generic power domains, latency tolerance through Quality of Service (QoS) mechanisms, and asynchronous power management operations. Learn how these various features, while individually straightforward through the device model APIs, create complexity when they interact with each other in real-world scenarios. This presentation serves as a continuation of previous discussions on Linux power management, expanding the breadth of coverage to encompass the wide range of power management features that have evolved within the Linux kernel over time.
